SHEET-METAL B ULBOUS ROOFING-TILE.

SPECIFICATION forming part of Letters Patent N 0. 511,387, dated December 26, 1893.

Application filed May 13, 1892. Renewed May 29,1893- Serial No. 475.984. (No model.)

To all whom it may concern:

Be it known that I, JAMES WHITE, a citizen of the United States, residing at Brooklyn, Kings county, New York, have invented certain new and useful Improvements in Sheet- Metal Bulbous Roofing-Tiles, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention consists in an improved form of sheet metal tile and in a cap of special form adapted to harmonize with the same when laid in conjunction upon the roof. The tile is in part like the so-called Spanish earthenware tile, butwith the lower end of the arch swelled into a bulbous form, the swell or bulb upon the tile being adapted to produce a striking contrast of light and shade when a series of such tiles are overlapped upon the roof. The adjacent edges of the tiles may be joined by any convenient means, and when nails are employed to secure the joint their heads may be protected from the weather by a cap consisting in a concave strip with bulbs formed upon the same at intervals in correspondence with the bulbs upon the tiles. To form the weather joint at the upper end of each tile, an auxiliary bulb is formed thereon over which the lower end of the superposed tile is placed.

The construction will be understood by ref erence to the annexed drawings, in which- Figure 1 is a perspective view of a single tile. Fig. 2 is a plan of fourtiles laid together with the cap laidover the middle joint of the tiles. Fig. 3 is a section on line 00, 0c, in Fig. 2, with the roof board under the tiles. Fig. 4 is an end view of two tiles (laid upon the roof board) with V-shaped channels bent in their edges, and a supporting strip of wood inserted beneath the middle joint. Fig. 5 is an edge view of one of the tiles with the end of the bulb closed up as is desirable at the lower end of the roof; the lowest tile in Fig. 8 having the bulb closed in a similar manner. Fig.6 is a longitudinal section on line 31, 1 in Fig. 2; andFig. 7 is a crosssection of the cap on line 5, z, in Fig. 2 with the bulb shown in the rear; and Fig. Sis an end view of the cap with the bulb closed up.

a is the main body of the tile, of arched form, with parallel edges ,or flanges formed with V-shaped channels I). The lower end of the body is swelled in Width and height forming a bulb a.

The tile is formed at its lower end with an arch or opening 0 of the sameshape as the body a, and an auxiliary swell or bulb 0. is formed at the upper end of the tile, over which the lower end of the superposed tile may be hooked, as shown in Fig. 3, where two tiles are shown in section upon the roofing boards d. The transverse joints of the tile are'thus thoroughly protected from the weather, and the longitudinal joints are shown formed by overlapping the channels 1) upon a strip of wood e having a V-shaped groove in the top corresponding in shape and dimensions with the channels; as shown in Fig. 4. The flanges in which the channels are formed are nailed through the strip, to the boards cl, nail holes f being shown upon the flanges in Fig. 2. The cap consists in a concave stripgshown in section in Fig. 7, adapted to cover the channels and the nail heads therein, as shown in Fig. 4, and formed with bulbs g at regular intervals to correspond with the bulbs a as the tiles are laid upon the roof. Such correspondonce is clearly shown in Fig. 2 where the bulbs upon the tiles and the cap appear in straight lines across the group of tiles, the cap lying midway in the gutter, between the ridges upon the tiles, as shown also in Fig. 4. The concave body of the cap is made of suitable width to cover the joint as shown in Fig. 4, and thus protects the joints from the weather. The cap may be secured by nails f shown in Fig. 2, the heads of which may be rendered tight by solder; or the cap may be secured by bent cleats which avoid the perforation of the cap, as claimed in my application Serial No. 426,104, filed March 23, 1892.

The tiles intended for use along the lower edges of the roof are closed at the bottom end a as shown in Fig. 5, and upon the tile at the lower end of Fig. 3 as there is no use at such point for the opening c; and a better finish is produced by a closed end upon the tile.

The cap may be made iustrips of any convenient length adapted to cover the longitudinal joint between six, eight or ten of the tiles, and the bulb at the lower end g of the cap may be closed as shown in Fig. 8, to produce the same finish at the lower edge of the roof as the closed end 01, of the tile shown in Fig. 5.

It will be readily seen that the bulbous tile produces a more striking contrast of light and shade when laid upon the roof than a tile with parallel body, and that it also permits the bodya of the tile as shown in Fig. 3, to lie parallel with the roof boards and with the flanges at the edges of the tile upon which the joints are made.

The formation of the bulbs upon the cap which protects the joint, produces an ornamental efiect in the gutters between the several rows of tiles, and thus heightens the contrast and ornamental efiect of the entire construction.

I do not claim the joint shown herein for uniting the edges of the tiles by nailing the flanges having V- shaped channels upon a grooved strip 6, as I have claimed the same in a pending application Serial No. 426,104, filed March 23, 1892. A large sheet of metal may also be stamped in imitation of many such tiles in a single piece, as claimed in my application Serial No. 427,451, filed April 2, 1892,in which case the edges of the sheet may be united by any suitable joint, and the cap 9 may be used for ornamental efiect between the several rows of imitation tiles when the sheets are laid upon the root. In such a construction the cap may be formed separately from the large sheet and secured in the gutters by nails or other fastenings; but it is obvious that an imitation of the cap with the bulbs g formed thereon at suitable points, may be formed by stamping directly in the gutters and thus avoid forming the cap sepa rately and fastening thereon, or perforating the sheet to secure the cap. In any case, where the cap is made separately its transverse joints are formed the same as those of the tiles by forming an auxiliary bulb at the upper end of the cap over which the bulb at the lower end would be hooked in the same manner as the bulbous tiles.

Having thus set forth the nature of my invention, what I claim herein is- 1. The sheet metal tile having arched body a with bulbous swell a at the lower end, and auxiliary bulbous swellat the upper end, as and for the purpose set forth.

2. The joint cap, for use with bulbous tiles, having the concave body g with bulbs g formed at regular intervals thereon, as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
